花生是我国重要的油料作物,也是嗜钙作物。为了探讨施钙对种植在酸性红壤下的花生根系内生细菌多样性的影响,本研究对不同处理、不同生育期的花生植株根系内生细菌基因组进行16SrRNA基因V3–V4区深度测序,分析种植于酸性红壤中施钙处理和对照下花生植株根系微生物群落结构。结果发现,根系内生菌群落中克雷伯氏菌属（Klebsiella）与肠杆菌属（Enterobacter）在所有样品组中均为优势属且相对丰度较高;花针期不同处理下假单胞菌属（Pseudomonas）与赖氨酸芽孢杆菌属（Lysinibacillus）在施钙组中相对丰度显著高于对照组,而劳尔氏属（Ralstonia）的相对丰度在施钙组中显著降低; Network共发生网络分...

Peanut is an important economic crop and calcium-loving crop in China. In order to explore the effect of calcium application on the diversity of endophytic bacteria in peanut roots planted in acid red soil, the genomes of endophytic bacteria in peanut roots of different treatments and different growth stages were deeply sequenced by 16SrRNA gene V3-V4 region, and the root microbial community structure of peanut plants planted in acid red soil and control was analyzed. The results showed that Klebsiella and Enterobacter were the dominant genera ...
